# diffAssoc()

The diffAssoc method compares the collection against another collection or a plain object based on its keys and values. This method will return the key / value pairs in the original collection that are not present in the given collection:

const collection = collect({
  color: 'orange',
  type: 'fruit',
  remain: 6,

const diff = collection.diffAssoc({
  color: 'yellow',
  type: 'fruit',
  remain: 3,
  used: 6,


// { color: 'orange', remain: 6 };
